Cranking noise? What could it be?

[tmas73]

Since I replaced my cranks and pedals I have some noise while riding. My bike is a converted KTM Mountain Bike with a 48V 750W Bafang BBS02B Mid Drive Motor.I also tighten the rings that secure the Motor. I loosend them again while troubleshooting but the noise still happens. I have a video of the issue. I also hope this is the right threat.

Thanks
